    Field Report - Understanding coater blade angle vs. loading tube pressure

    For a given blade tip bevel, when load tube pressure is increased, the blade angle will decrease, resulting in the blade running on its heel for a while. This, along with the additional bending pressure at the blade tip, will reduce coat weight. It is important to understand the interaction between blade angle, blade tip angle and loading tube pressure.

    Field Report - Size press roll wear, a case study

    A P&W paper machine suffered from excess wear on the back edge of the bottom size press roll. The problem was traced to the size press synchronization shaft. When the shaft was replaced, the roll wear problem went away.

    Field Report - Measuring applied and residual coat weight on applicator rolls

    Starch and coating is applied to the applicator roll using a rotating rod. The amount of coating applied to the roll is the most important variable for good coat weight control. This article describes a method of measuring the wet film on the fly across the size press, using a simple measurement tool.

    Field Report - Controlling coater blade beam deflection

    Coater beams deflect due to coating temperatures, paper temperatures and the temperature of the environment. Newer and wider coating machines are equipped with beam heating/cooling chambers that can be controlled to maintain a straight beam and hence better coat weight profiles.
